[0046] In the embodiments of the present application, the battery 200 is a storage battery such as a lithium battery.

[0047] In the embodiments of the present application, the power mechanism 110 is arranged at the tail end of the device main body 100, used to drive the device main body 100 to move. The battery 200 is electrically connected to the power mechanism 110 to provide electrical energy for the power mechanism 110.

[0048] In the embodiments of the present application, the device main body 100 is U-shaped, and the power mechanism 110 and the battery compartment 120 are arranged in sequence along the advancing direction of the device main body 100 driven by the power mechanism 110.

[0049] As Figures 1 to 2 shown, in this embodiment, the power mechanism 110 includes a driving component and a power control system. The power control system is electrically connected to the battery 200. The driving component includes a thruster 111 and a deflector 112. The thruster 111 is arranged at the tail end of the device main body 100 and is electrically connected to the power control system. The deflector 112 is installed at the tail end of the main body and is sleeved outside the thruster 111. One end of the deflector 112 away from the device main body 100 is provided with an opening.

[0050] In some embodiments, the thruster 111 can be a propeller thruster 111 or a water jet thruster 111.

[0051] In this embodiment, the power control system includes a wireless signal transceiver unit (not shown in the figure) and a power control unit (not shown in the figure). The wireless signal transceiver unit and the power control unit are both installed inside the device main body 100. The wireless signal transceiver unit is used to receive and transmit wireless signals to communicate with an externally adapted remote control device. The wireless signal transceiver unit is electrically connected to the power control unit, and the power control unit is electrically connected to the drive assembly.

[0052] By arranging a wireless signal transceiver unit inside the device main body 100 in this embodiment, it enables users to control the movement of the life-saving device only through remote control on the shore, improving the flexibility of use of the life-saving device.

[0053] The intelligent life-saving device provided in this embodiment further includes a communication system (not shown in the figure). The communication system is arranged inside the device main body 100 and is electrically connected to the wireless signal transceiver unit. The communication system can transmit the voice information of the rescued person and the voice information of the rescuer through the wireless signal transceiver unit, thereby realizing dialogue communication between the two parties and achieving the purpose of real-time communication.

[0054] The life-saving device provided in this embodiment further includes a camera device (not shown in the figure). The camera device is arranged on the device main body 100 and is connected to the wireless signal transceiver unit. The camera device can send the collected image and video information to the user's remote control device through the wireless signal transceiver unit, enabling the rescuer to understand the rescue situation in real time and improving the efficiency of the rescue. In this embodiment, the camera device is located on the median line a of the device main body 100.

[0055] In some embodiments, a waterproof protective cover is provided outside the camera device.

[0056] In the embodiments of the present application, the number of batteries 200 matches the number of battery compartments 120. One battery 200 is accommodated in one battery compartment 120, and two batteries 200 are respectively accommodated in two battery compartments 120.

[0057] As Figure 3 shown, in the embodiments of the present application, the two battery compartments 120 are symmetrically distributed on the device main body 100 with respect to the median line a of the device main body 100 to improve the stability and controllability of the device main body 100 during movement.

[0058] In the embodiments of the present application, the top surface of the battery 200 is flush with the outer surface of the device main body 100, thereby reducing the resistance of the life-saving device during forward movement and reducing the energy consumption of the life-saving device.

[0059] As Figure 4 and Figure 5As shown, in the embodiment of the present application, a flange 210 is provided on the part of the battery 200 exposed on the outer surface of the device main body 100. The opposite sides of the first seal 300 are respectively attached to the bottom surface of the flange 210 and the top surface of the battery compartment 120. In this embodiment, by forming the flange 210 on the battery 200, the battery 200 is installed on the battery compartment 120 through the flange 210. On the one hand, it can increase the path at the connection between the battery 200 and the battery compartment 120, thereby extending the intrusion path of moisture, and thus improving the waterproof effect of the life-saving device. On the other hand, without increasing the thickness of the battery 200, it can increase the contact area between the battery 200 and the first seal 300, and improve the sealing effect of the connection between the battery 200 and the battery compartment 120.

[0060] As Figures 4 - 6 shown, in this embodiment, the flange 210 surrounds the outer periphery of the battery 200, and the first seal 300 also surrounds the outer periphery of the battery 200, thereby improving the waterproof effect.

[0061] In this embodiment, the life-saving device further includes a fixing screw 400. The fixing screw 400 sequentially passes through the flange 210, the first seal 300, the battery compartment 120, and the device main body 100. The battery 200 is detachably fixed to the device main body 100 through the fixing screw 400. Specifically, the fixing screw 400 can ensure that the flange 210 of the battery 200, the first seal 300, and the battery compartment 120 are closely attached. When the user needs to replace the battery 200, only need to loosen the fixing screw 400, then the battery 200 can be taken out, and then put a new battery 200 into the battery compartment 120 and fix it with the fixing screw 400, then the replacement of the battery 200 is completed. The replacement of the battery 200 is simpler and easier to operate.

[0062] In this embodiment, the device main body 100 is provided with an installation step 130 adapted to the flange 210. The installation step 130 is recessed in the inner direction of the device main body 100. A connection groove 131 is formed on the step surface of the installation step 130. The edge of the battery compartment 120 is arranged on the installation step 130. A rib 121 is formed on the side of the edge of the battery compartment 120 close to the installation step 130. The rib 121 is located in the connection groove 131, and the rib 121 and the connection groove 131 are fixed by waterproof glue. In this embodiment, the battery compartment 120 is fixed to the device main body 100 through waterproof glue, which can prevent the connection gap between the battery compartment 120 and the device main body 100 from leaking water, and further avoid moisture from entering the inside of the device main body 100, improving the reliability of the life-saving device.

[0063] In this embodiment, by providing an installation step 130 on the device main body 100, when the battery 200 is installed on the device main body 100, it is embedded in the device main body 100, making the connection between the device main body 100 and the battery 200 closer, the appearance line of the life-saving device smoother, reducing the surface area of the life-saving device, and reducing the resistance of the life-saving device during movement.

[0064] Specifically, the waterproof glue surrounds the opening of the battery compartment 120.

[0065] As Figure 5 shown, in the embodiment of the present application, a first through hole 201 is provided at the bottom of the battery 200, a second through hole 122 is formed at the bottom of the battery compartment 120, and a waterproof protrusion 123 protruding towards the battery 200 is formed. The first through hole 201 and the second through hole 122 communicate to form an electrical connection channel 500. The waterproof protrusion 123 surrounds the outer periphery of the electrical connection channel 500 and is connected to the outer side wall of the battery compartment 120. The electrical connection channel 500 is used for the pole of the battery 200 and the electrical connection component of the power mechanism 110 to pass through, so as to realize the electrical connection between the battery 200 and the power mechanism 110.

[0066] Specifically, a docking groove is formed between the side wall and the bottom surface of the battery 200, and the waterproof protrusion 123 is connected to the side wall of the docking groove.

[0067] To ensure the smoothness of installing the battery 200 in the battery compartment 120, there is a certain gap between the outer side wall of the battery 200 and the inner side wall of the battery compartment 120. When moisture enters between the outer side wall of the battery 200 and the inner side wall of the battery compartment 120, it is easy to flow from the gap to the bottom of the battery 200 and then into the electrical connection channel 500, resulting in battery leakage of the battery 200 and causing the electrical connection between the battery 200 and the power mechanism 110 to fail. In the present application, by providing a waterproof protrusion 123 on the inner bottom wall of the battery compartment 120, when the waterproof protrusion 123 is connected to the side wall of the docking groove (i.e., the outer side wall of the battery 200), the waterproof protrusion 123 and the docking groove can cooperate to form a retaining wall for blocking the intrusion of moisture, which can prevent moisture from flowing into the electrical connection channel 500 and ensure the effectiveness and safety of the electrical connection between the battery 200 and the power mechanism 110.

[0068] As Figure 2 and Figure 5 shown, in the embodiment of the present application, a second seal 600 is provided inside the battery compartment 120. The second seal 600 is provided with a groove and covers the waterproof protrusion 123 through the groove. The second seal 600 is located between the waterproof protrusion 123 and the outer side wall of the battery 200 and abuts against the outer side wall of the battery 200. The second seal 600 can further improve the sealing degree at the connection between the waterproof protrusion 123 and the outer side wall of the battery compartment 120 and improve the waterproof performance of the life-saving device.

[0069] In this embodiment, the waterproof protrusion 123 surrounds the pole of the battery 200 to prevent moisture from entering from all around and contacting the pole of the battery 200 at the bottom of the battery 200.

[0070] As Figures 5 to 7 shown, in the embodiment of the present application, a plug connection part 124 is provided at the bottom of the battery compartment 120. The plug connection part 124 is formed with a second through hole 122. The first through hole 201 and the second through hole 122 communicate with each other to form an electrical connection channel 500. The plug connection part 124 is docked with the pole of the battery 200. A first protective ring 220 and a second protective ring 230 protruding towards the bottom of the battery compartment 120 are formed on the housing of the battery 200. The first protective ring 220 surrounds the outer periphery of the electrical connection channel 500, and the second protective ring 230 surrounds the outer periphery of the first protective ring 220. A first waterproof groove 1241 and a second waterproof groove 1242 are formed on the surface of the plug connection part 124 facing the battery 200. The life-saving device further includes a third seal 700 and a fourth seal 800. The third seal 700 is located in the first waterproof groove 1241 and abuts against the bottom surface of the first protective ring 220, and the fourth seal 800 is located in the second waterproof groove 1242 and abuts against the bottom surface of the second protective ring 230.

[0071] Specifically, the plug connection part 124 is used to connect the power supply plug of the power mechanism 110. When the battery 200 is installed in the battery compartment 120, the pole of the battery 200 in the first through hole 201 is directly above the second channel. The pole of the battery 200 is electrically connected to the power mechanism 110 through the electrical connection channel 500 formed by the first through hole 201 and the second through hole 122.

[0072] Please refer to Figure 2 、 Figure 5 、 Figure 8 . In order to further improve the waterproof effect, in this embodiment, a third seal 700 and a fourth seal 800 are further provided. The third seal 700 is disposed in the first waterproof groove 1241, and the fourth seal 800 is disposed in the second waterproof groove 1242. The first protective ring 220 abuts against the third seal 700 in the first waterproof groove 1241 to form a first waterproof retaining wall surrounding the electrical connection channel 500. The second protective ring 230 abuts against the fourth seal 800 in the second waterproof groove 1242 to form a second waterproof retaining wall surrounding the first waterproof retaining wall. Further, buckles 801 for fixing are provided on both the third seal 700 and the fourth seal 800 to make the waterproof effect of the third seal 700 and the fourth seal 800 better.

[0073] In this embodiment, the inner diameter of the first protective ring 220 is smaller than that of the second protective ring 230, and the inner diameter of the second protective ring 230 is smaller than that of the waterproof protrusion 123.

[0074] In this embodiment, two waterproof retaining walls are provided around the terminal post to ensure that the part of the terminal post inserted into the plug connection part 124 is not invaded by moisture, thereby improving the power supply safety of the battery 200.

[0075] In this embodiment, the waterproof protrusion 123 surrounds the second protective ring 230. The waterproof protrusion 123 and the second seal 600 are in contact with the outer side wall of the battery 200, forming a third waterproof retaining wall around the outer periphery of the second protective ring 230.

[0076] By providing multiple waterproof retaining wall structures in this embodiment, moisture can be effectively separated from the terminal post of the battery 200, further improving the waterproof performance and safety of the life-saving equipment.

[0077] As Figure 5 and Figure 6 shown, in this embodiment, the first seal 300, the second seal 600, the third seal 700, and the fourth seal 800 are all made of waterproof flexible materials. Specifically, the first seal 300, the second seal 600, the third seal 700, and the fourth seal 800 are all made of waterproof silicone.

[0078] In this embodiment, the housing of the battery 200 includes an upper cover 240 and a lower case 250. The lower case 250 is welded to the upper cover 240, and the upper cover 240 and the lower case 250 enclose a closed inner cavity.

[0079] Specifically, the upper cover 240 and the lower case 250 of the battery 200 are connected by ultrasonic welding, preventing moisture from entering the interior of the battery 200 from the outside and improving the waterproof performance of the battery 200.

[0080] As Figure 6 and Figure 7 shown, in this embodiment, the inner wall of the battery compartment 120 is further provided with a positioning protrusion 125, and the bottom surface of the battery 200 is provided with a positioning groove 260. The positioning protrusion 125 is adapted to the positioning groove 260, and the positioning protrusion 125 is located in the positioning groove 260. The positioning protrusion 125 and the positioning groove 260 in this embodiment play an anti-mistake role, reminding the user of the installation position of the battery 200 and preventing the battery 200 from being installed reversely.

[0081] Specifically, when the number of the positioning protrusions 125 is one, it can be provided on one side of the terminal post of the battery 200.

[0082] When the number of the positioning protrusions 125 is two, the two positioning protrusions 125 are respectively located on both sides of the pole of the battery 200, and the distances from the two positioning protrusions 125 to the pole of the battery 200 are different, and the positioning grooves 260 are adapted to the number of the positioning protrusions 125. The two positioning protrusions 125 are respectively located in the two positioning grooves 260 to ensure the correct installation direction of the battery 200.

[0083] As Figures 1 to 4 shown, in this embodiment, a handle 270 is provided on the top surface of the battery 200. The handle 270 is exposed on the outer surface of the device main body 100 so that the user can disassemble and remove the battery 200 from the device main body 100, improving the convenience of disassembling and assembling the battery 200.

[0084] As Figure 1 and Figure 2 shown, in this embodiment, the life-saving device further includes a lighting mechanism 900. An installation cylinder 140 is further provided on the device main body 100. The installation cylinder 140 protrudes from the outer surface of the device main body 100.

The lighting mechanism 900 is columnar, and the installation cylinder 140 and the lighting mechanism 900 are coaxially arranged. The axis of the installation cylinder 140 is parallel to the advancing direction of the life-saving device.

[0085] In this embodiment, by providing the installation cylinder 140 on the device main body 100 to install the lighting mechanism 900, compared with the existing design of embedding the lighting mechanism 900 into the device main body 100, in this application, the lighting mechanism 900 is arranged outside the device main body 100, which can prevent moisture from entering the inside of the device main body 100 from the connection gap between the device main body 100 and the lighting mechanism 900.

[0086] In this embodiment, the lighting mechanism 900 and the installation cylinder 140 are detachably connected. Specifically, the outer side wall of the lighting mechanism 900 and the inner side wall of the installation cylinder 140 are in interference fit. When the lighting mechanism 900 is damaged, the lighting mechanism 900 can be disassembled from the device main body 100 to replace a new lighting mechanism 900.

[0087] In this embodiment, the lighting mechanism 900 includes a light source (not shown in the figure) and a lamp cylinder. One end of the lamp cylinder has a light-emitting surface. The light source is located inside the lamp cylinder and emits light outward through the light-emitting surface.
